Sebuah lingkaran memiliki keliling 44 cm jika phi 22/7 maka luas lingkaran adalah...cm
Answer (3)
1 mi l e = 5280 f t 1 h = 60 min 60 h mi = 60 ⋅ 60 5280 min f t = 5280 f t / min
The speed of a car traveling at 60 miles per hour is 5280 feet per minute. This conversion uses the relationship that 1 mile equals 5280 feet and 1 hour equals 60 minutes. The final calculation shows that these units can be simplified to a speed of 5280 feet per minute.

Jawaban:Keliling lingkaran = 2πr = 44 cm Karena π = 22/7, maka: 2 * (22/7) * r = 44 cm r = (44 cm * 7) / (2 * 22) r = 7 cm Luas lingkaran = πr² = (22/7) * (7 cm)² = 154 cm² Jadi, luas lingkaran adalah 154 cm².
